Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

Researchers compare two nerve blocks for adults having outpatient shoulder surgery. One is the standard interscalene block, which can cause arm weakness and breathing problems. The other is a more selective anterior suprascapular nerve block. The trial tests whether the selective block controls pain as well as the standard one, using pain scores at 6 hours after surgery as the main measure.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
two ultrasound-guided nerve blocks: interscalene block and anterior suprascapular nerve block, both using ropivacaine
What this could lead to
If the more selective block controls pain as well as the standard one, patients could get similar relief with fewer side effects such as arm weakness and breathing trouble.
What could go wrong
The selective block may not control pain as well as the standard block, especially in the first hours after surgery. This is a single-center trial of 100 people, so results may not apply everywhere.
